Summary
This study monitored 50 healthy seamen using electrocardiogram (ECG) and found that 36% experienced premature heartbeats. Most arrhythmias were low intensity, indicating generally good cardiovascular health in this group.
Area of Science:
- Cardiology
- Occupational Health
Context:
- Seamen are a unique occupational group with potential exposure to stressors.
- Cardiovascular health in maritime professionals requires specific investigation.
- Holter monitoring provides continuous electrocardiogram (ECG) data for arrhythmia detection.
Purpose:
- To assess the prevalence of cardiac arrhythmias in healthy seamen using 24-hour Holter ECG monitoring.
- To characterize the types and incidence of premature beats and other rhythm disturbances in this population.
- To establish a baseline of cardiovascular electrophysiological findings in a healthy maritime workforce.
Summary:
- Fifty healthy seamen (aged 29-55) underwent 24-hour Holter ECG monitoring after comprehensive cardiovascular assessment.
- Premature beats were detected in 36% of subjects: supraventricular (8%), atrioventricular-junction (8%), and ventricular ectopic beats (18%).
- Sinus bradycardia was observed in 28%, with rare instances of sinus tachycardia; overall arrhythmia intensity was low.
Impact:
- Provides crucial data on the cardiac electrophysiological status of healthy seamen.
- Highlights the prevalence of generally benign arrhythmias in this occupational group.
- Informs occupational health guidelines and future research on cardiovascular risks in maritime workers.
